Description

Die Erfindung betrifft einen Seitenplanenspanner, insbesondere zum Spannen von Planen eines Nutzfahrzeugaufbaus, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a side tarpaulin tensioner, in particular for tensioning tarpaulins on a commercial vehicle body, according to the preamble of patent claim 1.

Ein Seitenplanenspanner der vorgenannten Art ist in der EP 3 435 547 A1 beschrieben. Dieser besteht aus einem, einen U-förmigen Querschnitt aufweisenden Spannhebel, der über einen Schwenkbolzen schwenkbar mit den Seitenwangen eines Grundkörpers verbunden ist. Der Grundkörper weist eine zwischen den Seitenwangen angeordnete Vorderwange auf, die der Aufnahme einer Gewindebolzen-Muttern-Kombination dient, deren Gewindebolzen durch eine Durchführung eines Haltebolzens durchführbar ist, der an einer zu spannenden Plane festlegbar ist. An dem Spannhebel ist ein Haken schwenkbar befestigt. Der Haken kann hinter einem Schenkel des Rahmenprofils eines Nutzfahrzeuges eingehängt werden und dient als Widerlager. In seiner offenen Stellung befindet sich der Spannhebel in einer vollständig aufgeschwenkten Stellung. In dieser Stellung wird der Haken an einem Schenkel des Rahmenprofils eingehängt. Beim Schließen des Spannhebels erfolgt eine gegeneinander gerichtete Relativbewegung zwischen dem an dem Spannhebel angelenkten Haken und dem mit der Gewindestange verbundenen, an der Plane befestigten Block, so dass die Plane im Zuge dieser Bewegung gespannt wird. Um ein ungewolltes Öffnen des Spannhebels zu vermeiden sind an die Seitenwangen Nasen angeformt, die in dieser geschlossenen jeweils eine an den Grundkörper angeformte Federzunge hintergreifen.A side tensioner of the aforementioned type is in the EP 3 435 547 A1 described. This consists of a clamping lever with a U-shaped cross section, which is pivotably connected to the side walls of a base body via a pivot pin. The base body has a front cheek arranged between the side cheeks, which serves to accommodate a threaded bolt-nut combination, the threaded bolt of which can be passed through a passage of a retaining bolt, which can be fastened to a tarpaulin to be tensioned. A hook is pivotally attached to the clamping lever. The hook can be hung behind a leg of the frame profile of a commercial vehicle and serves as an abutment. In its open position, the cocking lever is in a fully pivoted open position. In this position, the hook is hung on a leg of the frame profile. When the tensioning lever is closed, there is a mutually directed relative movement between the hook articulated on the tensioning lever and the block attached to the tarpaulin, which is connected to the threaded rod, so that the tarpaulin is tensioned in the course of this movement. In order to avoid an unintentional opening of the clamping lever, lugs are formed on the side cheeks, which each engage behind a spring tongue formed on the base body when closed.

Seitenplanenspanner der vorgenannten Art haben sich in der Praxis bewährt. Es hat sich jedoch gezeigt, dass die Rastverbindung zwischen Nasen und Federzungen insbesondere bei neuen Seitenplanenspannern manchmal schwer zu lösen sind. Darüber hinaus besteht die Gefahr einer Ermüdung der an den Grundkörper angeformten Federzungen bei fortschreitendem Gebrauch.Side curtain tensioners of the aforementioned type have proven themselves in practice. However, it has been shown that the latching connection between the lugs and the spring tongues is sometimes difficult to release, particularly in the case of new side curtain tensioners. In addition, there is a risk of fatigue of the spring tongues formed onto the base body as use progresses.

Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, einen Seitenplanenspanner bereitzustellen, der eine verbesserte Sicherung vor selbsttätigem Öffnen aufweist. Gemäß dieser Erfindung wird diese Auflage durch einen Seitenplanenspanner mit den Merkmalen des kennzeichnenden Teils des Patentanspruchs 1 gelöst.Against this background, the object of the invention is to provide a side curtain tensioner that provides improved protection against automatic opening. According to this invention, this requirement is solved by a side curtain tensioner having the features of the characterizing part of patent claim 1.

Mit der Erfindung ist ein Seitenplanenspanner bereitgestellt, der eine verbesserte Sicherung vor selbsttätigem Öffnen aufweist. Dadurch, dass wenigstens ein Rastelement durch eine an dem Spannbügel angeordnete Federspange gebildet ist, die in wenigstens eine an dem Grundkörper angeordnete Rastaufnahme einrastbar ist, ist eine zuverlässige Rastverbindung gewährleistet.With the invention, a side curtain tensioner is provided which has improved protection against automatic opening. Because at least one latching element is formed by a spring clip which is arranged on the clamping bracket and which can be latched into at least one latching receptacle arranged on the base body, a reliable latching connection is ensured.

In Weiterbildung der Erfindung ist die Federspange lösbar mit dem Spannbügel verbunden. Hierdurch ist ein einfacher Austausch einer defekten oder ermüdeten Federspange ermöglicht.In a further development of the invention, the spring clip is detachably connected to the clamping bracket. This enables a simple replacement of a defective or worn-out spring clip.

In Ausgestaltung der Erfindung weist die Federspange an ihren beiden Schenkeln eine U-förmige Ausformung auf, die jeweils mit einer an dem Grundkörper angeordneten Rastaufnahme verrastbar ist. Hierdurch ist eine Vorspannwirkung in Richtung der Rastaufnahme erzielt.In an embodiment of the invention, the spring clip has a U-shaped formation on its two legs, which can be locked in each case with a snap-in receptacle arranged on the base body. This achieves a prestressing effect in the direction of the locking receptacle.

In weiterer Ausgestaltung der Erfindung greifen die freien Enden der U-förmigen Ausformungen jeweils in eine an dem Spannbügel angeordnete Öse ein. Hierdurch ist eine einfache Montage der Federspange ermöglicht.In a further embodiment of the invention, the free ends of the U-shaped formations each engage in an eyelet arranged on the clamping bracket. This allows for easy assembly of the spring clip.

In Weiterbildung der Erfindung ist der die beiden Schenkel der Federspange verbindende Querbügel nach außen gewölbt ausgebildet. Hierdurch ist eine Aufhebung der Vorspannung der U-förmigen Ausformungen durch eine Kraft auf den Querbügel ermöglicht. Vorzugsweise ist die Federspange derart ausgebildet, dass der nach außen gewölbte Querbügel über den Spannbügel hervorragt.In a further development of the invention, the crossbar connecting the two legs of the spring clip is curved outwards. This allows the prestressing of the U-shaped formations to be eliminated by a force on the crossbar. The spring clip is preferably designed in such a way that the outwardly curved crossbar protrudes over the clamping bar.

In Ausgestaltung der Erfindung sind die U-förmigen Ausformungen jeweils durch eine Abwinklung mit einem Schenkel der Federspange verbunden. Hierdurch ist eine Positionierung der U-förmigen Ausformungen nahe am Übergang zu den Schenkeln in der Rastaufnahme ermöglicht, wodurch eine hohe Vorspannung erzielbar ist. Bevorzugt begrenzt die Abwinklung einen Winkel von zwischen 15° und 25°, insbesondere einen Winkel von zwischen 17° und 23°. Alternativ kann die Abwinklung (83) auch U-förmig ausgebildet und an dem Schenkel (81) im Wesentlichen rechtwinklig angestellt sein.In an embodiment of the invention, the U-shaped formations are each connected to a leg of the spring clip by a bend. This enables the U-shaped formations to be positioned close to the transition to the legs in the snap-in receptacle, resulting in high prestressing is achievable. The bend preferably delimits an angle of between 15° and 25°, in particular an angle of between 17° and 23°. Alternatively, the bend (83) can also be U-shaped and positioned essentially at right angles on the leg (81).

Erfindungsgemäß ist an dem Grundkörper eine Vorderwange zur Aufnahme eines Befestigungsmittels zur Verbindung mit einer Plane angeordnet und das wenigstens eine zweite, als Rastaufnahme ausgebildete Rastelement ist durch eine in der Vorderwange angeordnete Nut gebildet. Hierdurch ist eine orthogonal zur Ausformung der Federspange ausgerichtete Rastaufnahme erzielt.According to the invention, a front panel for receiving a fastener for connection to a tarpaulin is arranged on the base body, and the at least one second latching element designed as a latching receptacle is formed by a groove arranged in the front panel. This achieves a snap-in receptacle that is aligned orthogonally to the shape of the spring clip.

In Weiterbildung der Erfindung ist an die Vorderwange wenigstens ein abgewinkelter Rastflügel angeformt, in dem die Nut eingebracht ist. Hierdurch ist die Ausbildung der Rastaufnahme durch einen einfachen Stanzbiegevorgang ermöglicht, wodurch die Herstellung vereinfacht ist.In a development of the invention, at least one angled detent wing, in which the groove is introduced, is formed onto the front panel. This enables the locking receptacle to be formed by a simple stamping and bending process, which simplifies production.

In Ausgestaltung der Erfindung ist die Vorderwange mit einer Schräge versehen, die in der Nut mündet. Hierdurch ist ein einfaches Hineingleiten der als Rastelement fungierenden Federspange in die Nut erzielt.In an embodiment of the invention, the front panel is provided with a bevel which ends in the groove. As a result, the spring clip, which acts as a latching element, simply slides into the groove.

In Ausgestaltung der Erfindung sind an dem Spannhebel benachbart zu dessen Seitenflügeln gegenüberliegend zwei Führungslaschen angeformt, die derart zueinander abgewinkelt sind, dass sie einen Einschub für die Federspange ausbilden. Hierdurch ist eine einfache Montage der Federspange erzielt.In an embodiment of the invention, two guide tabs are formed on the tensioning lever adjacent to its side wings opposite each other and are angled relative to one another in such a way that they form a slot for the spring clip. This achieves a simple assembly of the spring clip.

In weiterer Ausgestaltung der Erfindung ist die Federspange aus einem Federdraht durch Umformung hergestellt. Hierdurch ist eine kostengünstige Herstellung erzielt.In a further embodiment of the invention, the spring clip is made from a spring wire by forming. In this way, a cost-effective production is achieved.

Der als Ausführungsbeispiel gewählte Seitenplanenspanner besteht im Wesentlichen aus einem Grundkörper 1, in dem ein Spannbügel 2 schwenkbar gelagert ist, der eine Federspange 8 aufnimmt und der wiederum schwenkbar mit einem Haken 3 verbunden ist. An dem Grundkörper 1 ist eine Bördelmutter 4 befestigt, die eine Hammerkopfschraube 6 aufnimmt, die durch die Durchführung eines Planenwinkels 5 geführt ist.The side curtain tensioner selected as an exemplary embodiment consists essentially of a base body 1 in which a tensioning bracket 2 is pivotably mounted, which accommodates a spring clip 8 and which in turn is pivotably connected to a hook 3 . A flanged nut 4 is fastened to the base body 1 and receives a hammer head screw 6 which is guided through the implementation of a tarpaulin bracket 5 .

Der Grundkörper 1 ist im Ausführungsbeispiel als Blechstanzbiegeteil ausgebildet. Er besteht im Wesentlichen aus einer Grundplatte 11, an dessen beiden Längsseiten jeweils eine Seitenwange 12 rechtwinklig angestellt ist. In den Seitenwangen 12 ist jeweils eine erste Bohrung 13 sowie eine beabstandet zu dieser angeordnete Verplombungsbohrung 14 eingebracht. Die fluchtend zueinander angeordneten ersten Bohrungen 13 dienen der Aufnahme eines Achsbolzens 7 zur schwenkbaren Lagerung des Spannbügels 2. Die Grundplatte 11 ragt über die Seitenwangen 12 hinaus, wobei angrenzend an die Seitenwangen 12 in die Grundplatte 11 beidseitig ein Freischnitt 111 eingebracht ist. Der hierdurch begrenzte, auskragende Verklemmsteg 112 unterstützt die Verklemmung des S-Schlages der zu spannenden Plane über den Haken 3.In the exemplary embodiment, the base body 1 is designed as a stamped and bent sheet metal part. It essentially consists of a base plate 11, on each of whose two long sides a side cheek 12 is placed at right angles. A first bore 13 and a spaced-apart sealing bore 14 are made in each of the side walls 12 . The aligned first bores 13 serve to receive an axle bolt 7 for the pivotable mounting of the clamping bracket 2. The base plate 11 protrudes beyond the side walls 12, with a cutout 111 being introduced into the base plate 11 on both sides adjacent to the side walls 12. The cantilevered clamping bar 112 delimited by this supports the clamping of the S-fold of the tarpaulin to be stretched over the hook 3.

An ihrem dem Verklemmsteg 112 gegenüberliegenden Ende ist an die Grundplatte 11 eine rechtwinklig abgewinkelte Vorderwange 15 angeformt, die mittig mit einer Bohrung versehen ist, durch die der Bördelkragen einer Bördelmutter 4 geführt ist, die sodann verbördelt ist, wodurch die Bördelmutter 4 an der dem Verklemmsteg 112 zugewandten Seite der Vorderwange 15 befestigt ist. Zur Stabilisierung der Vorderwange 15 ist diese mit Sicken 151 versehen. Beidseitig der Vorderwange 15 sind an dieser gegenüberliegend winklig zwei Rastflügel 16 angeformt, die jeweils eine Nut 161 aufweisen. Oberhalb der Nut 161 sind die Rastflügel 16 mit einer Schräge 162 versehen.At its end opposite the Verklemmsteg 112 a right-angled front cheek 15 is formed on the base plate 11, which is provided with a hole in the middle through which the flared collar of a flared nut 4 is guided, which is then crimped, whereby the flared nut 4 on the Verklemmsteg 112 facing side of the front cheek 15 is attached. The front panel 15 is provided with beads 151 to stabilize it. On both sides of the front cheek 15 two detent wings 16 are formed at an angle opposite each other and each have a groove 161 . The latching wings 16 are provided with a bevel 162 above the groove 161 .

Der Spannbügel 2 besteht im Wesentlichen aus einer Deckplatte 21, die an ihren beiden Längsseiten mit rechtwinklig zu dieser angestellten Seitenflügeln 22 versehen ist, welche die Deckplatte 21 in ihrer Länge überragen.

Weiterhin ist wiederum beabstandet zur zweiten Bohrung 24 eine Verplombungsbohrung 25 in den Seitenflügeln 22 angeordnet. An ihrer der Verplombungsbohrung 25 zugewandten Seite sind in die Deckplatte 21 gegenüberliegend zwei nach innen gerichtete Ösen 26 zur Aufnahme der freien Enden der Schenkel 81 der Federspange 8 ausgeformt. Weiterhin sind an die Deckplatte 21 an ihrer den Ösen gegenüberliegenden Seite zwei gegenüberliegend angeordnete Führungslaschen 27 angeformt, die parallel zur Innenseite der Deckplatte 21 verlaufend abgewinkelt sind, wodurch ein Einschub gebildet ist.The clamping bracket 2 consists essentially of a cover plate 21, which is provided on both of its long sides with side wings 22 which are set at right angles to the latter and protrude beyond the cover plate 21 in terms of their length. In the section of the side wings 22 that protrudes beyond the cover plate 21, a first bore 23 and a second bore 24, spaced apart from this, are introduced into the latter at each end. Furthermore, a sealing hole 25 is arranged in the side wings 22 at a distance from the second hole 24 . On its side facing the sealing hole 25 two inwardly directed eyelets 26 for receiving the free ends of the legs 81 of the spring clip 8 are formed in the cover plate 21 opposite. Furthermore, two oppositely arranged guide tabs 27 are formed on the cover plate 21 on its side opposite the eyelets, which are angled to run parallel to the inside of the cover plate 21, whereby an insert is formed.

Der Haken 3 ist im Wesentlichen in Form eines gekrümmten Blechstreifens ausgebildet, der an einem Ende in einen Flanschabschnitt 31 übergeht. Der Flanschabschnitt 31 ist im Wesentlichen eben ausgebildet und an seinen Längsseiten mit rechtwinklig nach innen angestellten Ösen versehen, über die der Haken 3 schwenkbar mit dem Spannbügel 2 verbunden ist. Zur Stabilisierung des Hakens 3 ist dieser an der Außenseite seines gekrümmten Bereichs mit Sicken 32 versehen.The hook 3 is essentially in the form of a curved sheet metal strip, which merges into a flange section 31 at one end. The flange section 31 is essentially flat and is provided on its long sides with eyelets set inwards at right angles, via which the hook 3 is pivotably connected to the clamping bracket 2 . To stabilize the hook 3, it is provided with beads 32 on the outside of its curved area.

Die Federspange 8 ist in Figur 3 gezeigt. Sie ist im Ausführungsbeispiel aus einem Federstahldraht mittels eines Umformprozesses hergestellt und weist zwei gegenüberliegend angeordnete Schenkel 81 auf, die über einen nach außen gewölbt ausgebildeten Querbügel 82 verbunden sind. Die beiden Schenkel 81 sind gegenüberliegend mit einer Abwinklung 83 versehen, die im Ausführungsbeispiel mit dem Schenkel einen Winkel von 20° begrenzt. An die Abwinklung 83 der Schenkel 81 schließt sich jeweils eine in Richtung des gegenüberliegenden Schenkels 81 gerichtete U-förmige Ausformung 84 an, die im Ausführungsbeispiel mit der Abwinklung 83 einen Winkel von 33° einschließt.The spring clip 8 is in figure 3 shown. In the exemplary embodiment, it is made from spring steel wire by means of a forming process and has two legs 81 arranged opposite one another, which are connected via a crossbar 82 which is curved outwards. The two legs 81 are oppositely provided with an angled portion 83 which defines an angle of 20° with the leg in the exemplary embodiment. The bend 83 of the legs 81 is followed by a U-shaped formation 84 directed in the direction of the opposite leg 81, which in the exemplary embodiment encloses an angle of 33° with the bend 83.

Der Spannbügel 2 ist derart in dem Grundkörper 1 eingebracht, dass dessen Seitenflügel 22 innen an den Seitenwangen 12 des Grundkörpers 1 anliegen, wobei durch die miteinander fluchtenden ersten Bohrungen 13, 23 der Seitenwangen 12 sowie der Seitenflügel 22 ein Achsbolzen 7 geführt ist. Der Achsbolzen 7 bildet die Schwenkachse, um welche der Spannbügel 2 relativ zum Grundkörper 1 verschwenkbar ist. Alternativ ist auch eine schwenkbare Lagerung über durch die ersten Bohrungen 13, 23 geführte Nieten möglich.The clamping bracket 2 is inserted in the base body 1 in such a way that its side wings 22 rest on the inside of the side walls 12 of the base body 1, with an axle bolt 7 being guided through the aligned first bores 13, 23 of the side walls 12 and the side wings 22. The axle bolt 7 forms the pivot axis about which the clamping bracket 2 can be pivoted relative to the base body 1 . Alternatively, a pivotable mounting via rivets guided through the first bores 13, 23 is also possible.

Die Federspange 8 ist mit ihren Schenkeln 81 zwischen die Deckplatte 21 und die Führungslaschen 27 eingeschoben, wobei die freien Enden der U-förmigen Ausformungen 84 der Schenkel 81 in die Ösen 26 der Deckplatte 21 eingreifen. Der nach außen gewölbt ausgebildete Querbügel 82 ragt dabei über die Deckplatte 21 hervor.The spring clip 8 is inserted with its legs 81 between the cover plate 21 and the guide tabs 27 , the free ends of the U-shaped formations 84 of the legs 81 engaging in the eyelets 26 of the cover plate 21 . The outwardly curved crossbar 82 protrudes over the cover plate 21 .

Der Spannbügel 2 ist derart in dem Grundkörper 1 positioniert, dass bei einem Verschwenken des Spannbügels 2 in Richtung der Vorderwange 15 (Schließrichtung) die U-förmigen Ausformungen 84 der an dem Spannbügel 2 befestigten Federspange 8 entlang der Schrägen 162 der Rastflügel 16 gleiten und in die Nuten 161 vorgespannt eingreifen. Dabei fluchten die Verplombungsbohrungen 14, 25 vom Grundkörper und Spannbügel, sodass ein Zollverschluss ermöglicht ist. Der Haken 3 ist derart zwischen den Seitenflügeln 22 des Spannbügels 2 angeordnet, dass dessen Ösen mit den zweiten Bohrungen 24 der Seitenflügel 22 fluchten, wobei durch diese ein weiterer Achsbolzen 7 geführt ist, über den der Haken 3 relativ zum Spannbügel 2 verschwenkbar gelagert ist. Durch die Bohrung der Vorderwange 15 hindurch ist eine Hammerkopfschraube 6 in die Bördelmutter 4 eingeschraubt, die zuvor durch die Durchführung des Planenwinkels 5 hindurchgeführt ist.The clamping bracket 2 is positioned in the base body 1 in such a way that when the clamping bracket 2 is pivoted in the direction of the front cheek 15 (closing direction), the U-shaped projections 84 of the spring clip 8 attached to the clamping bracket 2 slide along the bevels 162 of the locking wings 16 and in the grooves 161 engage biased. The sealing holes 14, 25 of the base body and clamping bracket are aligned, so that a customs seal is possible. The hook 3 is arranged between the side wings 22 of the clamping bracket 2 in such a way that its eyelets are aligned with the second bores 24 of the side wings 22, through which another axle bolt 7 is guided, via which the hook 3 is pivotably mounted relative to the clamping bracket 2 is. A hammer head screw 6 is screwed through the bore of the front cheek 15 into the flared nut 4 , which was previously passed through the passage of the tarpaulin bracket 5 .

Der Spannbügel 2 ist in seiner geschlossenen Position über die U-förmigen Ausformungen 84 der Federspange 8, die in die Nuten 161 der Rastflügel 16 der Vorderwange 15 eingreifen, fixiert, sodass ein selbsttätiges Öffnen zuverlässig verhindert ist. Durch einen Druck auf den gewölbten Querbügel 82 der Federspange 8 können die U-förmigen Ausformungen 84, die endseitig von den Ösen 26 der Deckplatte 21 des Spannbügels 2 aufgenommen sind, zusammengedrückt werden, wodurch diese aus den Nuten 161 herausbewegt werden. Ein einfaches Verschwenken des Spannbügels in eine Öffnungsstellung ist nun ermöglicht.The clamping bracket 2 is fixed in its closed position via the U-shaped formations 84 of the spring clip 8, which engage in the grooves 161 of the latching wings 16 of the front panel 15, so that automatic opening is reliably prevented. By applying pressure to the curved crossbar 82 of the spring clip 8, the U-shaped formations 84, which are accommodated at the ends by the eyelets 26 of the cover plate 21 of the clamping bracket 2, can be pressed together, as a result of which they are moved out of the grooves 161. A simple pivoting of the clamping bracket into an open position is now possible.

Im Ausführungsbeispiel gemäß Figur 4 ist eine alternative Ausgestaltung der Federspange 8 angeordnet. Hierbei sind die Abwinklungen 83 der Schenkel U-förmig ausgebildet und im Wesentlichen rechtwinklig abgewinkelt an die Schenkel angestellt. An die Abwinklungen 83 schließen sich ebenfalls rechtwinklig angestellt U-förmige Ausformungen 84 an, die auf derselben Ebene wie die Schenkel 81 der Federspange 8 angeordnet sind. Die freien Enden der U-förmigen Ausformungen 84 greifen in an der Deckplatte 21 angeformte Ösen 26 ein.In the embodiment according to figure 4 an alternative embodiment of the spring clip 8 is arranged. Here, the bends 83 of the legs are U-shaped and are positioned essentially at right angles to the legs. The bends 83 are also set at right angles to U-shaped formations 84 which are arranged on the same plane as the legs 81 of the spring clip 8 . The free ends of the U-shaped formations 84 engage in eyelets 26 formed on the cover plate 21 .

Bei einem Verschwenken des Spannbügels 2 in Richtung der Vorderwange 15 (Schließrichtung) gleiten die die U-förmigen Abwinklungen 83 der an dem Spannbügel 2 befestigten Federspange 8 entlang der Schrägen 162 der Rastflügel 16 und greifen in die Nuten 161 vorgespannt ein. Die U-förmigen Ausformungen 84 bilden Federelemente aus, die bei Betätigung der Federspange 8 durch Druck auf den Querbügel 82 vorgespannt werden und so eine selbsttätige Rückbewegung der Federspange 8 in ihre Ausgangslage nach Betätigung bewirken.When the clamping bracket 2 pivots in the direction of the front cheek 15 (closing direction), the U-shaped bends 83 of the spring clip 8 attached to the clamping bracket 2 slide along the bevels 162 of the locking wings 16 and engage in the grooves 161 in a prestressed manner. The U-shaped formations 84 form spring elements which are pretensioned when the spring clip 8 is actuated by pressure on the crossbar 82 and thus bring about an automatic return movement of the spring clip 8 into its starting position after actuation.
